Metabolism of proteins Which of the following substances is excreted by sweat glands in response to the breakdown of proteins and the formation of ammonia?

A. Sebum

B. Urea

C. Lysozymes

D. Water

Answer Explanation:

Proteins are nitrogen-based compounds, which when broken down release ammonia. Ammonia is a toxic substance to the body, and sebaceous glands coverts it to urea.

Therefore, the Correct Answer is B.

The requested answer is aa.
Q #3: Which of the following statements best supports the hypothesis that viruses can cause cancer?

A. Cellular DNA has sequences related to viral sequences

B. Cancerous and normal cells share genetic sequences

C. Genes that regulate cell division are found in some viruses

D. Viruses and cancer cells both replicate rapidly

Answer Explanation

Cancer is a condition caused by unregulated division of abnormal cells in parts of the body. For a virus to survive in an organism, it must enter into the host’s cell and take control of the cell’s most activities in order to be able to reproduce and replicate.

Some of the viruses achieve this by inserting their DNA or RNA to that of the host cell. This has a highly likelihood of affecting the DNA or RNA of a host (living organism) which alters their genes, which may lead to host cells becoming cancerous.

For this reason, viruses can cause cancer because the genes that regulate cell division in host cell are found in some viruses.
